topicPectin Gut Microbiome Randomized Trial
claimBackground Imidazole propionate (ImP), a microbial metabolite of histidine, may impair glucose metabolism, but its relevance to coronary heart disease (CHD) risk and potential diet-microbiota regulations remain unclear.

topicPectin Gut Microbiome Randomized Trial
claimWe aimed to examine prospective associations of plasma ImP levels and histidine intake with CHD risk, to identify ImP-predicting gut microbes, and to investigate diet-microbiome interactions influencing ImP levels.
